The present invention relates generally to a device for mounting an electrical appliance such as a television, radio, and the like to a surface such as a wall or ceiling. More specifically, the device relates to an improved device for mounting an arm, which further supports the appliance, to a wall or other surface.
As shown in U.S. Pat. No. 5,127,617 to Bergetz, mounting assemblies typically function by first securing the appliance to a support means which is attached to an arm which is, in turn, secured to a mounting means which has been attached to a surface. Generally, the arm first passes through a lower bracket and then an upper bracket. Once the arm passes through the upper bracket, the assembly must be suspended until a cotter pin is inserted through the arm or a flange is attached. The appliance and arm are then lowered until the pin or flange engages and comes to rest on the top bracket. This secures the entire assembly by preventing any further downward movement. The arm may also be fabricated from a pipe, which allows the entire assembly to pivot in a circular path.
Since the assembly must be suspended in an unlocked position, two persons are generally required to perform this task: one to hold the assembly in a suspended position, the other to insert the pin or attach the flange. By contrast, my invention simplifies the installation procedure by providing an arm that has a pre-attached stop. During installation, the arm is first inserted through an upper retainer and then the arm is lowered until the stop engages the lower retainer which prevents any further downward movement. By locating the locking function on the second retainer, the need to suspend the assembly before locking is eliminated, which makes the assembly of my invention by one person possible. My invention also reduces the cost of manufacture. By using fewer pieces in the mount's construction a savings in the amount of materials used and lower labor costs are realized.
Accordingly, it is an object of my invention to provide a mount which includes an arm with a pre-attached stop that facilitates the ease of use and reduces the difficulty of locking the assembly to a mount. It is a further object of my invention to provide a mount which is more economical to manufacture.

FIG. 8 is a perspective view of an embodiment that uses a plate or tab which has been attached to the cover as the locking means and does not require the use of a keeper.
FIG. 1 is a perspective view of my invention in a locked position. The device comprises a housing 10, arm 30, keeper 40 and stop 50 which may be an annular flange that is axially disposed on arm 30. Housing 10 includes a first retainer 11 having aperture 12 and opposingly located second retainer 13 having a slot 20 which is configured to permit the transverse insertion and removal of arm 30 and is sized to permit the longitudinal movement of arm 30. Both retainers are connected to opposing side walls 14 and 15 as well as back wall 16 with apertures 16a for mounting housing 10 to a surface. Second retainer 13 further includes retaining edge or shoulder, 17 which contains slots 18 and 19.
Although the first and second retainers form opposing ends of an integrate of housing 10 in the preferred embodiment, an alternate embodiment could include retainers that are separate and discrete structures. By adapting each retainer to be mountable to a surface, the same objects and advantages of my invention can be achieved without the use of a housing. Such an embodiment may be useful in situations where a housing is not desired or where it would be impractical to manufacture a housing.
Arm 30 is typically made from a pipe which allows it to pivot move, or rotate in an arcuate path positioned in the retainers. As shown in FIG. 4, arm 30 is typically bent into a cantilevered shape which results in the formation of an appliance support end 31, to which an appliance support means 33 is attached and opposing mounting end 34 which terminates in free end 3. Mounting end 34 is further divided into a first portion 35 and a second portion 36. Stop 50 is attached to second portion 36 and is spaced from free end 37 whereby it defines an arm segment 38 having a fixed length. Stop 50 may also be a ring that has been welded to arm 30, but it may also be attached by any other mechanical fastening means.
Keeper 40, as shown in FIGS. 4 and 5, includes aperture 39 and plate 41 which has formed from it two opposing side flanges 42 and 43. Flanges 42 and 43 further include clips 44 and 45, which maintain keeper 40 and stop 50 together in assembled adjacent relation. Also formed from plate 41 are two opposing downwardly directed tabs or flanges 46 and 47 which include holes 48 and 49.
In operation, once housing 10 is secured to a surface the preferred embodiment is assembled by inserting arm 30 into aperture 39 of keeper 40 and positioning keeper 40 next to stop 50. Clips 44 and 45 are then placed over stop 50 maintaining the adjacent relation keeper 40 and stop 50. Next, appliance support means 33 is secured to arm 30 and then an appliance is attached.
Arm 30 and the attached appliance are then lifted and first portion 34 of arm 30 is inserted into aperture 12 of first retainer 11 of housing 10, which has been sized to receive free end 37 thereby permitting longitudinal movement while restraining arm movement. Arm 30 is next placed into a position where arm 30, keeper 40, and stop 50 may be then transversely inserted into slot 20 of second retainer 13 and then lowered as a unit. Since second retainer 13 has been spaced from first retainer 11 a distance less than arm segment 38, upon lowering, plate 41 contacts retaining edge or shoulder 17 and keeper 40 provides a bearing surface between shoulder 20 and stop 50 that prevents any further downward movement of arm 30 any further downward movement of arm 30. At the same time, tabs 46 and 47 run through slots 18 and 19 which inhibit horizontal movement. Locking pins (not shown) or some other type of mechanical fastening means are then placed through holes 48 and 49 which lock arm 30 and keeper 40 into place and generally prevent any upward movement while still permitting arm 30 to rotate within the retainers when the lock is actuated. Since housing 10 may be configured to have an open side which permits receipt of arm 30, a cover 60 may be placed on housing 10 to cover the working mechanisms and to present a more attractive device.
An alternate embodiment is shown in FIGS. 7 and 8. This embodiment comprises arm 90 with attached stop 92 and housing 100. As described above, arm 90 is a cantilevered pipe that is made and operates in the same manner as arm 30 which was previously described. Housing 100 further includes first retainer 102 containing aperture 103 and opposingly located second retainer 104 which are connected by opposing sidewalls 106 and 108. Connected to both retainers and sidewalls is backwall 110, which includes apertures 112 for securing housing 110 to a surface. Second retainer 104 further includes retaining edge or shoulder 107, which is sized to allow passage of arm 90 and block the passage of stop 92 by abuttingly engaging stop 92.
Housing 100 further includes a locking means, which is shown as pin 122 and apertures 123 and 125 in FIG. 7. Another locking means could be a plate may be a plate, tab, or some other type of extended projection 132 which is integral with or attached to cover 130. As shown in FIG. 8, plate 132 is adapted to fit around arm 90 yet cover stop 92.
The assembly and operation of this embodiment is virtually identical to the assembly and operation of the embodiment described above. Arm 90 is first inserted through aperture 103, which prevents any horizontal movement of arm 90. Arm 90 and stop 92 are then positioned and lowered down onto retaining edge 107, which prevents any further downward movement of arm 90 and stop 92.
In the embodiment using pin 122 as a locking means, pin 122 is inserted into apertures 123 and 125 located on housing 100. It is necessary to position apertures 123 and 125 so that when pin 122 is inserted, it comes into close proximity with an outer edge of arm 90 and upper surface of stop 92 so as to prevent any unwanted upward and horizontal movement of arm 90 and stop 92.
In the embodiment in which the locking means is plate 132 located on cover 130, it is necessary to form a semicircular aperture 136 that is slightly larger than arm 90 yet smaller than stop 92. Such a configuration, once properly positioned over stop 92 and against arm 90, prevents any vertical and horizontal movement that could disengage the device. Cover 130 and plate 132 are then locked into place by pins 134 and 156 which can be inserted through apertures 140, 142,144 and 146, all of which are located in housing 100.
It should be understood that various changes and modifications to the preferred embodiment described would be apparent to those skilled in the art. Changes and modifications can be made without departing from the spirit and scope of the present invention and without diminishing its intended advantages. It is, therefore, intended that such changes and modifications be covered by the following claims.
